LC100 Hardgrove Grindability Tester measures relative ease of pulverization of coals compared to standard coals in accordance with ASTM D409 Hardgrove Machine resulting Hardgrove Grindability Index (HGI) provides a measure of energy required in a grinding process or a measure of yield for a given energy input.
BW's pulverizers, found at power stations throughout the world. From our original E/EL ballandrace type pulverizers for lower capacity applications, to the latest BW Roll Wheel™ pulverizer capable of grinding up to 230,000 pounds of coal per hour (104,300 kg/hr), we set the standard for high availability, reliability and low maintenance.
Rod Ball Mills. The Ball/Rod mills are meant for producing fine particle size reduction through attrition and compressive forces at the grain size level. They are the most effective laboratory mills for batchwise, rapid grinding of mediumhard to very hard samples down to finest particle sizes.
